Matthew 24:1-3

1Jesus left the temple area and was going on His way when His disciples came up to Him to call His attention to the [magnificent and massive] buildings of the temple.

2And He said to them, “Do you see all these things? I assure you and most solemnly say to you, not one stone here will be left on another, which will not be torn down.”

3While Jesus was seated on the Mount of Olives, the disciples came to Him privately, and said, “Tell us, when will this [destruction of the temple] take place, and what will be the sign of Your coming, and of the end (completion, consummation) of the age?”
